Directories listed in allowed_directories in ~/.copilot/permissions-config.json do not suppress the "path outside your allowed directory list" prompt for shell commands.

Describe the bug

Directories listed in allowed_directories in ~/.copilot/permissions-config.json do not suppress the "path outside your allowed directory list" prompt for shell commands. /add-dir with the identical path fixes it for the session.

Startup log says it loaded:
[INFO] permissions::api_orchestrator] Applied persisted allowed directories {"count":2,"location_key":"..."} 
Probable cause: in app.js, addAdditionalDirectory() is only called inside the paths.add handler. hydrate_location_permission_directories applies persisted dirs to the native permission service but never performs that sync, so the path gate used for shell commands doesn't see them.
Secondary: the prompt's "Yes, and add these directories to the allowed list" option maps to {kind:"approve-for-session"} — the wording implies persistence it doesn't have.

Affected version

GitHub Copilot CLI 1.0.79.

Steps to reproduce the behavior

Repro: add an absolute dir to allowed_directories under a location key; start a session whose git root is that key; run a shell command reading a file under that dir → prompt appears. Run /add-dir  → no more prompts.

Expected behavior

No response

Additional context

No response

app.js から始め、paths.add ハンドラーの addAdditionalDirectory() と hydrate_location_permission_directories、および永続化されたディレクトリの起動パスを比較します。絶対パスの allowed_directories エントリで再現し、その下にあるファイルを読み取る shell コマンドを実行します。永続化されたディレクトリによって /add-dir と同様にパスのプロンプトが抑制され、プロンプトの文言がセッション限定の許可を正確に反映すれば完了です。
